What problem does it solve? Reviewing a branch or work-in-progress diff by hand is slow and inconsistent: reviewers miss broken callers, convention drift, spec deviations, and tests that would pass without the change. This Skill structures the review of any diff since a fixed point (commit, branch, tag, or merge-base) into four independent axes checked by parallel subagents, with findings written to disk and disposed as fixed, filed, or declined. ## Core Features & Use Cases - Four-axis parallel review: Correctness, Standards, Spec, and Tests reviewers run concurrently, each reading the full touched files and callers rather than the diff in isolation, and write reports to agent/reviews/<range>/. - Smell baselines: Ships SMELLS.md (Fowler-style code smells) and TEST-SMELLS.md (tautological expectations, indiscriminate inputs, mocked collaborators, and more) so reviews have a fixed baseline even when the repo documents no standards. - Light mode for specless work: Unspecced changes get a single reviewer combining the Correctness and Standards briefs, with no Spec axis. - Use Case: Ask to "review this branch against main" before merging; the Skill pins the merge-base, spawns the axis reviewers, aggregates their reports, and disposes each finding as a fix commit, a filed ticket, or a declined note. ## Quick Start Ask the agent to review the changes on the current branch since main using the code-review skill.
